Origin has built-in Bessel functions of both the First Kind and the Second Kind of order 0 and order1 in both LabTalk and OriginC:
J0(argument) Compute the Bessel function of the first kind of order 0
J1(argument) Compute the Bessel function of the first kind of order 1
Y0(argument) Compute the Bessel function of the second kind of order 0
Y1(argument) Compute the Bessel function of the second kind of order 1
so you should be able to J0(b*x), for example. Note that these are only real-valued functions, so if your 'i' indicates you are working with complex values, this would not work.
